Red and Purple - newbie

Start of this week was rough - 3 of my seedlings fell! I found out that they stretched too fast for light, so I increased the light intensity to 40% from 20% and buried them into more soil to prevent plants from leaning to sides. Also in the end of this week, i flushed the soil with water and nutrients, so roots can grow properly. Then I performed LST on all Red Poison, they seem to respond well. Tomorrow I’ll perform LST on the rest of flowers :)
